I don't know what has happened to our pool in the past year or so but please help me figure out how I can make it safer for the rest of the season. I'm pretty sure I need to have it drained/start over! We added soda ash per Paddock instructions but the free chlorine is not coming down despite totally removing the chlorinator for a week in 105+ degree sunny weather. Here's the numbers! Thanks in advance for any help you can provide so we can remain swimming this season (if possible!).
12,000 gallon plaster pool
Total Chlorine: 10
alkalinity, total: 100
Adjusted TA: 25
Copper- not tested but we have purple stains on our pool in a few locations so something is up here..
No green alge, no black, no pink slime
What has to happen? should we just be partially draining and re-adding water at this point since it is way too hot to totally drain here in Az?
Thanks again for any reponses! Neither I nor my husband know much about pools and obviously need to be educated. We've been busy working full time and raising toddlers so, sadly, our pool has suffered. ;(
